With six days left in Subject 13's Kickstarter campaign, Paul Cuisset and Microïds have announced today that Linux fans have been heard, and that a Linux version of the game will be added alongside PC, Mac, and mobile platforms if the game’s basic Kickstarter goal of $40,000 is met. Additional platforms such as Oculus Rift are waiting to be added if stretch goals are met.

In Subject 13, players will take on the role of Franklin Fargo, a physics professor who has become a recluse after the tragic death of his fiancée. One morning, he wakes up in an abandoned underground scientific facility with no external contact other than a mysterious voice. The voice calls him "Subject 13." Fargo’s goal is to not only set himself free but discover the true reasons for his imprisonment—can he escape from the prison of his past?

Subject 13 is full of secret caches and mechanisms that the player must discover, analyze and activate. The game’s difficulty gradually ramps up as the story unfolds, promising a game open to all virtual adventurers. If the first puzzles serve as an introduction most players can quickly solve, completing the entire adventure should be a real challenge even for the experts.
